* ipa-prop.c (ipa_print_all_jump_functions): Moved here from
ipa-cp.c and split into two functions.
(ipa_print_node_jump_functions): New function.
(compute_scalar_jump_functions): New function.
(type_like_member_ptr_p): New function.
(compute_pass_through_member_ptrs): New function.
(fill_member_ptr_cst_jump_function): New function.
(determine_cst_member_ptr): New function.
(compute_cst_member_ptr_arguments): New function.
(ipa_compute_jump_functions): Complete rewrite, a tuplified one.
* ipa-prop.h (enum jump_func_type): Make explicit that we depend
on IPA_UNKNOWN being zero. Added value IPA_CONST_MEMBER_PTR.
(struct ipa_member_ptr_cst): New structure.
(union jump_func_value): New field member_cst.
* ipa-cp.c (ipcp_lat_is_insertable): New function.
(ipcp_lattice_from_jfunc): Produces bottom lattices for unhandled
jump function types.
(ipcp_print_all_lattices): Slight fprintf rearrangement.
(ipcp_print_all_structures): Call ipa_print_all_jump_functions
instead of ipcp_print_all_jump_functions.
(ipcp_create_replace_map): Do not check for CONST_VALUE_REFs.
(ipcp_insert_stage): Use ipcp_lat_is_insertable, create replace maps
only for replacable scalars.
